Aseptic medical instrument packaging with supporting peelable flaps

ABSTRACT

The present invention discloses an aseptic medical instrument packaging with supporting peelable flaps; the present invention gets the supporting peelable flaps by adding a material playing a supporting role and harder than the rest parts to the extending part outside a sealing edge of the peeling side of the packaging or adopting a material harder than the rest parts on the extending part outside a sealing edge of the peeling side of the packaging; a groove is carved in the junction between the outer edge of the sealing edge of the peeling side of the packaging; the material playing the supporting role comprises hard plastic, metal and paper. According to the present invention, a soft cover of the packaging is prevented from being inwards curled in the peeling process of the packaging; and when one or two peeling sides exist, the differentiation degree of the peeling side will be increased, such that medical staff can conveniently find the peeling side.

TECHNICAL FIELD

The present invention belongs to the field of equipment packaging, in particular to an aseptic medical instrument packaging with supporting peelable flaps.

BACKGROUND ART

Many clinically used articles need an aseptic packaging, for example, aseptic gloves, aseptic gauze, plaster, etc. The article 5.1.9c of the first part of Packaging for Terminally Sterilized medical instruments of ISO 11607-2006 which is applied at present prescribes that the peeling characteristics shall be continuous and homogenous, without delamination or tearing of the material that can affect aseptic opening and presentation. The article 7.3.5 of the Packaging for Terminally Sterilized Medical Instruments of GB/T 19633-2005 prescribes that in package-peeling, the fiber falling and cracking or breaking of the packaging material shall be in a specified limitation of a manufacturer to ensure no influence on the use of medical instruments. However, these standards including pharmaceutical Industry Standards YY/T 0698 do not prescribe an inward curling degree of the peeling side of the packaging for the terminally sterilized medical instruments in peel-open. At present, there are many types of medical aseptic packagings, for example, a pre-formed rigid tray is provided with a die-cut lid, flexible peel pouch, sterilization bag, header bag, form/fill/seal (FFS) and four-side-sealing (4SS) process, etc., (appendix A3 of the first part of IS011607-2006), and one of the upper packaging surface and lower packaging surface of the packaging is or both are soft usually. These aseptic packagings are provided with a peeling side/edge, i.e., an extending part (non-aseptic, a gripper part) outside the sealing edge is wider than the other three sides. Of course, there are packagings with multiple peeling sides. In clinical practice, an operator peels the aseptic packaging, the operation standard requires that the peel-open flap is peeled while two faces (both soft) or one face (soft) of the packaging is outwards turned and curled. In fact, when the peelable flap of the aseptic packaging is longer and cannot be grasped by hands or the operator peels the package in a hasty condition, due to the influence of the non-peeled parts at two adjacent sides of the peelable flap, the part not grasped on the soft cover is inwards turned and curled, the germ-carrying extending part outside the sealing edge contacts with and contaminates contents, thereby increasing an infection risk. Such poor influence, like the damage, sealing fiber and scrap falling of the packaging, will lead to a failure of the sterility of the contents. Therefore, there is a need of putting forward a new concept: a controllable soft cover peeling direction of the packaging for the aseptic medical instruments.

SUMMARY OF THE INVENTION

Aiming at the defects of the prior standards and prior art of the present invention, according to the new concept “a controllable soft cover peeling direction of the packaging for the aseptic medical instruments”, the present invention provides an aseptic medical instrument packaging with supporting peelable flaps.

The aseptic medical instrument packaging with supporting peelable flaps gets the supporting peelable flaps by adding a material playing a supporting role and harder than the rest parts to the extending part outside a sealing edge of the peeling side of the packaging or adopting a material harder than the rest parts on the extending part outside a sealing edge of the peeling side of the packaging; the material playing the supporting role comprises hard plastic, metal and paper; the supporting peelable flap plays a supporting role like that of a flagpole when the packaging is peeled, to guide the soft cover of the packaging to be turned and curled toward a desired direction.

The hard plastic is phenolic plastic, polyurethane plastic, epoxy plastic, unsaturated polyester plastic, furan plastics, or plastic made of organic silicon resin, propenyl resin or modified resin.

The corners of the material playing a supporting role, harder than the rest parts and added to the extending part outside a sealing edge of the peeling side of the packaging are passivated to avoid the damage of the packaging in a storage and transportation process.

The corners of the material playing a supporting role, harder than the rest parts and adopted on the extending part outside a sealing edge of the peeling side of the packaging are passivated to avoid the damage of the packaging in a storage and transportation process.

The metal is aluminum, steel, iron, platinum or alloy.

A groove is carved in the junction between the outer edge of the sealing edge of the peeling side of the packaging and the extending part to facilitate peeling.

Beneficial effects: 1, the supporting peelable flap plays a supporting role like that of a flagpole when the packaging is peeled, and the soft cover of the packaging is prevented from being inwards curled to contaminate the contents; 2, when there are only one or two peelable flaps, the differentiation degree of the peeling side will be increased, such that medical staff can conveniently find the peeling side; 3, the present invention is close to clinical practice, finds the defects of the existing standards, and puts forwards the new concept “a controllable soft cover peeling direction of the packaging for the aseptic medical instruments”, and lays a foundation for our country to obtain certain right to speak in the high end field of establishment of international standards of packaging for terminally sterilized medical instruments.
